S&P 500 Index futures fell 0.3% as of 7:56 a.m. in New York as a selloff in the artificial-intelligence trade gathered speed and pushed investors toward the safety of bonds, Bloomberg Markets reported on October 15, 2026.
The move reflects growing caution among investors who had driven up AI-linked shares in recent months. As the selloff accelerated, traders shifted money out of riskier technology names and into government debt, a classic flight to safety that tends to weigh on equity futures ahead of the opening bell.
Several of the biggest US movers before the bell were tied to the AI and semiconductor theme. Shares of CoreWeave, Dell, Intel and Micron were among the names drawing attention in premarket trading, while Penske and FMC also featured on the list of notable movers.
The pre-market weakness comes as investors weigh the outlook for AI spending against valuations that have climbed sharply. Bloomberg's premarket coverage tracks these shifts so that traders can gauge where demand for the sector's most closely watched stocks may be heading when the regular session begins.
